This screencast follows on from the previous Mathematical Symbols in Word for Mac.

In this screencast, I show a fast method for typing mathematical expressions involving basic symbols (like × and ÷). This method doesn't require the mouse to navigate a menu nor does it require an Equation to be inserted.

Increasingly I am consuming media on my desktop computer rather than my TV when at home.

Numberphile, for example, publishes one or two videos a week that I want to watch. However, I've always found watching in the browser annoying. Two ways to improve the YouTube viewing experience are:

install an extension like ImprovedTube (for Chrome) which, as the name suggests, improves the experience of watching on YouTube - stops AutoPlay for example.

download YouTube videos to watch in a media player. There are online services and software that can do this. But you then have to wait for the download (rather than streaming) and I don't necessarily want a copy of the video once watched.

In the past, Maths teaching resources amounted to printed materials (be it a textbook, BLM). If the teacher didn't like what was available to them, they could hand-draw and Gestetner a more appropriate worksheet.

In 2009, Year 9 got their DER netbooks and now they are in Year 10. This year’s Year 9 does not have their netbooks yet, and so this gives teachers a little time to get their heads around the inclusion of netbooks into the classroom. This year, I’m teaching a 5.2 pathway Year 10 class (and a Year 9 5.2 class).

For NSWDET teachers, I’m sure you know of TaLe, and hopefully have seen some of the resources for the DER that have been published there. One category of resources has been called Laptop Wraps (they are also available publicly).

Reading blogs and networking on Twitter seem an obvious part of being a teacher. Yet when I take in to school a shiny new resource that I’ve received through one of these means, I usually get asked “where did you find this?”. The person behind the question is often thinking that I spend copious hours sitting at home in front of a computer “web surfing” or trying endless combinations of search terms in Google.

As I mentioned, the DER roll-out hit my classroom as we were in the midst of Algebra. Due to a tight program and exams shortly, I had to stick with a couple of topics which don’t really allow for “play” on the laptops as much as I would have liked.

A lot of the Algebra taught at the Stage 4 level is technique, and so matching activities work particularly well to practise and review skills.

Here’s a review of some of the ways I’ve found to make matching activities for use on the laptops.

Year 9 got their DER netbooks just before the end of Term 3. The first week of Term 4 will be the first time they have them in class, so I wanted to start term with some introductory activities, with a Maths focus.

Find graphics that represent things you do frequently in lessons (perhaps from clipart) and always use these when doing a similar activity. For example, a pen writing for when it’s time to start work or two people talking for discussion/group work. These help reinforce good habits and aid classroom management.

As a PBL school, we have lots of “Student Expectations” at our school for nearly all aspects of an ordinary day (entering the classroom, in the playground, walking through a corridor – we have narrow corridors, formal assembly). In a couple of weeks, there will be another aspect of the “ordinary day” – laptops. So, I’ve drafted some student expectations for the technology committee at my school to discuss.

Google Sketchup is one of the applications bundled on the DER netbooks being rolled out into NSW Public High Schools in Term 3. But as it’s free, you can download it now for Windows XP/Vista & Mac OS X.

I recently contributed some comments to the executive at my school about the DET roll-out expected to be happening soon. A slightly editted version is below. I’m really not sure where the executive are at with this roll-out, I haven’t heard much except from the computer coordinator – it’s a shame, or more accurately, it makes me nervous, because there is the potential for a lot of problems to arise from this roll-out if we’re not prepared. I’m republishing my comments because they might help you in engaging with your school about planning and preparation.

My previous post on having an IWB in my classroom was written about three weeks after it’s installation. Tomorrow, we’ve got an IWB consultant/trainer/type-person-thingy coming to school, and I was asked to share what I’ve been doing with the IWB. So I wrote a quick list.

With laptops rolling out shortly and projectors appearing in some classrooms, we should be thinking about collecting digital media for use as stimulus or investigation material. So, the other day when filling up my young daughter’s bottles, I took some pictures.

I wanted to play a multiplication bingo type game with a class the other day, so I grabbed two 10 sided dice (apparently you don’t need to call a single dice a “die” anymore) out of the cupboard. Then I thought… hey I have a projector and a laptop.

The NSWDET will shortly equip Year 9 students with a Lenovo S10e netbook as part of a program called “Laptops for Learning” (L4L). To me, if we are going to do this – then it’s time to include some good software on these machines and help out schools who cannot afford some of the more exciting applications.

When starting “Volume” with Year 8, we start by looking at cubic units and isometric drawings. This year, with an interactive whiteboard (although, these resources are also suited for use with just a projector or in a computer lab), I was able to use a couple of excellent online resources.

I need to learn to use GeoGebra because it looks like a fantastic app, it’s free and shortly our students will have their own netbooks, itching to use them. I find the best way to learn new software is to do something with it that you need.

I have watched with interest the Digital Education Revolution proposed by the Australia Government. Issues of cost seem to have been resolved and I’ve resigned myself to the fact that the NSWDET is pushing a one laptop fits all model (although I think it’s flawed). I’ve read the tender for the “DET Learning Device” and have even dissected it with my computing class. But today, 1st April – fitting really – a significant step to realisation has been taken with the announcement of the hardware and software to be supplied.

Some of the methods in this article do not work in Microsot Word for Mac 2011. Please see the updated post Mathematical Symbols in Word for Mac for a screencast describing the current best method (in my opinion).

Creating a maths worksheet in Microsoft Word without using the proper symbols does not present well – I’m sure you’ve seen 2 * 2 = 4 or 2 × 2 = 4 rather than 2 × 2 = 4. My previous post, Maths symbols in Word is one of the most popular on this site. In that post, I gave shortcuts for inserting mathematical symbols into Word – the post was specific to the Windows version of Word. As I’ve been a Mac user for a year, it’s time to make a similar post for Mac users.

Around this time each year, our programs have Year 8 and Year 10 looking at the Number Plane. For the end of the term, it’s nice timing, because it allows us to draw some pictures on the number plane. One favourite is the logos of various NRL
